Boost Your Website Performance With A WordPress Cache Plugin

WordPress Cache Plugin

WordPress is one of the most influential platforms preferred by most business owners to develop their online business. You can take various actions for optimising your WordPress site, but installing a cache plugin will hold the greatest efficiency on your page load time.  Once visitors get to your online presence, they have to request various information from the web host. They should send a request for JavaScript, Images and CSS. Additionally, they must retrieve your content from the WordPress database as well. Each of these activities adds to your entire loading time.

WordPress cache plugins deal with this problem by developing a static edition of your content and conveying it to the audiences. This surely decreases the load time of your site and you can observe progress within the whole website presentation of about ten times.

What are Cache Plugins?

A caching plugin creates an image of your website pages on your server. When a user visits your website, the server doesn’t create a dynamic page and serves it to the user. Instead, it takes that image and serves it to the user. This increases retention and reduces the time it will take to load the complete website at the client’s end. The served version is a lot lighter and doesn’t require processing the heavier WordPress PHP scripts.

Utilising WordPress Cache Plugins

Speed is important for every website. Not only is it a ranking factor, but it also helps visitors get the information from your website faster and interact with the website whether it’s buying something or getting the information they want.

We have a short span these days with so many options to choose from. We want to visit only those websites that can open within seconds so that we can get the information we want or make the required action.

Sadly, that’s not always the case and that’s why most visitors leave a website while it is still loading. On average, a website takes around five to seven seconds to load. This is just too much for a visitor. Because the attention span of a visitor is less than three seconds. 1, 2, 3… and the visitor will close the web page/hit the back button and try the second page on Google search.

So, what’s the solution? How to improve site performance so that visitors don’t leave your website?

That’s where cache plugins come to help. Let’s learn about these cache plugins in detail and understand how they can help you improve site performance and decrease the bounce rate.

Do You Need a Website Cache Plugin?

Yes, if your website has dynamic content that requires the webserver to process scripts before serving the page to the user, you can benefit from a good website caching plugin. A good website caching plugin will save you the cost of optimising your website for performance again and again. It will also fix most of the errors you get in the Core Web Vitals in the Google Search Console.

Website cache is important because it improves the efficiency of the server, reduces page load time, increases user retention, and lowers the site’s bounce rate.

Moreover, since the server doesn’t have to process heavy website scripts, it takes less bandwidth and puts a minimum load on the server.

Caching and Minifying Your Website

Whichever cache plugin you choose, make sure that it offers everything you need to make your site’s performance faster. A few features that a decent caching plugin should offer include:

Browser Caching: Browser caching allows your browser to store the content of the web page if you are a repeat visitor. When you open the website, instead of the server loading all the content, your content is loaded from the browser, reducing server load and increasing page performance.

Page Caching: The image of a page is stored on the server. When a new user visits it, the page cache is activated and it serves the user with that page instead of the server rendering it dynamically. This decreases page load time. Page cache is possible only for pages that get the most hit.

Gzip Compression: GZip compresses the page on the server side so that it is loaded on the browser faster. When a browser receives a compressed page, it decompresses it. For Gzip compression to work effectively, the page size should be below 1MB so that browsers can load and decompress it instantly.

Database Optimisation: A good cache plugin should also offer database optimisation so that the bloat is removed from the server and loads the website faster.

Lazy Loading: A simple technique of deferring the loading of images, scripts, and content that are not part of the header tag. Lazy loading offers faster page rendering and reduces Time to First Byte (TTFB).

JS/HTML Minification: Everyone writes JAVA scripts and HTML differently. With minification, all random spaces, unnecessary code, and comments are removed from the code files decreasing file size and increasing performance.

DNS Prefetching: Most websites get hosting from one host and domain from another host. With DNS prefetching, the connection time in connecting to the DNS is reduced.
